Trying to Diagnose Problem With a Garmin Fish Finder Need Some Help

521 Views 5 Replies 6 Participants Last post by  Seahunter
I have a Garmin 178C Sounder, and I'm having a problem with it cutting off. I've narrowed it down to when I reach behind and press on the power/data cable where it connects to the unit to the left or right, the unit will cut off.

While I was looking at the pin configuration on the back of the unit where the cord plugs into the back of the unit I noticed that one of the pins is about 3 millimeters lower than all of the rest of the pins. I was wondering if this could be my problem, maybe that pin got pushed in somehow, has anyone else seen a similar pin configuration on their unit?

Any suggestion on whether I should just fork up the $30 plus dollars for the new cord or try sending the unit back for diagnosis (which I'm sure is gonna cost me)?

Thanks, Dave

try gettting hold of the pin and see if it will pull back up gently i worked on aircraft for a leaving and we had this problem a lot if not take it to a electronic shop for boats they should have a pin installer and be able reposition the pin for you
If you can't find someone with a pin tool try using a roll pin with an ID diameter roughly the same size as the OD of the bent pin. I've used this method successfully in the field quite a few times.

If the pin has been pushed, back into the connector housing you can usually pull them back into position using a pair of needle nose pliers. A drop of super glue will hold the pin in position if need be.
